Carbohydrates Flashcards
This is the building block of rigid cell walls and woody tissues in plants.
Cellulose
This occur in all plants and animals and are essential to life.
Carbohydrates
These are the major source of carbohydrates
Plant products
What is the recommended carbohydrates?
60%
Has the molecular formula C6H12O6 or C6(H2O)6
Glucose
______________ are polyhydroxyaldehydes, polyhydroxyketones, or substances that give such compounds on hydrolysis.
Carbohydrates
What are the two functional groups of carbohydrates?
Hydroxyl and carbonyl group
What are the types of carbohydrates based on structure?
Monosaccharides, oligosaccharides, and polysaccharides
Starch, Dextrin, Glycogen, Cellulose, and Insulin are _________
Homopolysaccharides
Maltose, Lactose, Sucrose are ___________
Disaccharides
These are not water soluble and are not cystalline. They form colloidal suspensions instead of solutions. They are not sweet and must be digested before being absorbed.
Polysaccharides
Carbohydrates that cannot be hydrolyzed to simpler compounds
Monosaccharides
This contain at least
two and generally no more than a few linked
monosaccharide units.
Oligosaccharides
This test is given by reducing sugars. The formation of RED PRECIPITATE confirms the presence of reducing sugars.
Fehling’s Test
This test is used to determine the presence of carbohydrates or sugars in the substance.
Molisch’s Test
Who discovered the Molisch’s Test?
Hans Molisch
This test is to detect the presence of complex carbohydrates. The yellow-orange iodine will turn blue-black as it reacts with starch and the iodine solution will show no reaction with simple carbohydrates or sugars.
Iodine Test
This test is used to test for simple carbohydrates. It also allows us to detect the presence of sugars with a free aldehyde or ketone group.
Benedict’s Test
This test is a qualitative laboratory test used to distinguish between an aldehyde and a ketone.
Tollens Test
